background condition meaning in Chinese
背景条件
Examples
- Programming through inhibition of the background conditions
.可通过编程对背景条件进行抑制 - The internal causes include the background conditions of geography and geological environment
自然地理地质环境背景条件为内因，人类工程活动为外因。 - Background condition for fruit grading is simple . on the basis of stretch transform of gray level , gray image can be binarized ideally if given a overall gray segmentation threshold
水果分级的背景条件较为简单，在灰度拉伸变换的基础上，使用单一的全局阈值就可以进行较为理想的二值分割。 - ( 4 ) the intensity of the vertical movement of the air over the east of nwc , from the 1990s " , it tended to weaker , which is regarded as a dynamic background condition
( 4 )西北地区东部垂直运动的强弱具有一定的年代际变化， 90年代以来，强度趋于减弱，成为该区90年代降水减少的一个动力背景。 - The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition ; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event ; the subsidence flow at the middle and low tropospheric levels is favorable for the setting - up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region ; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event ; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation
结果表明：在中高层暖性高压脊及地面变性冷高压稳定维持的大尺度背景条件下，地表净辐射引起的近地层冷却是大雾过程的触发和加强机制；中低空下沉气流的存在有助于近地层的弱风条件和稳定层结的建立；低层暖平流的输入和边界层的浅层抬升是大雾长时间持续的原因；伴随冷空气南下的偏北大风是驱使大雾消散的动力因子。
